A NASA video takes you on a quick tour of the Centaurus A galaxy and its jets.
A network of radio telescopes scattered around the Southern Hemisphere has produced the best-ever view of cosmic jets erupting from a supermassive black hole at the center of another galaxy.
The new image shows a region of space less than 4.2 light-years across at the heart of Centaurus A, 12 million light-years away in the constellation Centaurus (of course). The galaxy, also known as NGC 5128 is anchored by a black hole as massive as 55 million suns. It's a huge radio source. In fact, if our eyes could see radio waves, Centaurus A would look nearly 20 times as big as the full moon, due to the giant lobes of radio-emitting matter spreading out from the galaxy itself.
The matter is streaming into the lobes via the particle jets that emanate from the black hole.
"These jets arise as infalling matter approaches the black hole, but we don't yet know the details of how they form and maintain themselves," Cornelia Müller, a doctoral student at the University of Erlangen-Nuremberg in Germany, said in a NASA image advisory released today.
Müller is the lead author of a study about the jets, appearing in the June issue of Astronomy and Astrophysics. She and her colleagues targeted Centaurus A with a network of nine radio telescopes in Africa, South America and Australia, known collectively as the Tracking Active Galactic Nuclei with Austral Milliarcsecond Interferometry project, or TANAMI. The telescopes joined forces to zoom in on the heart of the galaxy.

Left: The giant elliptical galaxy NGC 5128 is the radio source known as Centaurus A. Vast radio-emitting lobes (shown as orange in this optical/radio composite) extend nearly a million light-years from the galaxy. Right: The radio image from the TANAMI project provides the sharpest-ever view of a supermassive black hole's jets. This view reveals the inner 4.16 light-years of the jet and counterjet, a span less than the distance between our sun and the nearest star. Undetected between the jets is the galaxy's 55-million-solar-mass black hole.
"Advanced computer techniques allow us to combine data from the individual telescopes to yield images with the sharpness of a single giant telescope, one nearly as large as Earth itself," Roopesh Ojha of NASA's Goddard Space Flight Center explained.
The radio image shows features as small as 15 light-days across, which makes it the highest-resolution view of galactic jets ever made. Studying the jets in such detail should help astronomers figure out how they form — which would make Müller very happy.

Think about how long it took that matter to get that far out from the black hole. The radio waves might travel at the speed of light but not the matter. Not that it really matters. It's a matter for the scientists.
Can you say matter kiddies? I knew you could.
What is mind? Doesn't matter. What is matter? Never mind.
...and like deer in the headlights, people will watch this...as it spins slowly towards the earth...and sprays it with lethal doses of radiation, frying people where they stand in a fraction of a second...oh the horror...
happy 5/21 everybody (ROFLMAO)
But.. those are the bright souls of the trillions dying in that galaxy as they escape into heaven!
"In fact, if our eyes could see radio waves, Centaurus A would look nearly times wider than the full moon"
Missing a number in there... how many times wider?
MSNBC quality control
strikesmisses again!I see the mistake is STILL not fixed. I guess Alan Boyle figures since the end of the world is coming, there's no need to correct typos.
Well, it's fixed now. Really, maybe it was just an oversight. No need to get so angry about it. I get that many writers on MSNBC seem to go horrifically unedited, and many seem to have no writing skills to speak of, but Alan isn't one of them. Even excellent writers need editing, and these days most writers don't have that luxury, along with tight deadlines and busy schedules. I write for a newspaper doing special supplements, and we get no copyediting. I'm pretty solid with my final products, but sometimes even I goof.
I used to work at MSNBC and I count Alan Boyle as one of the few that I have some respect for. He was there at the beginning with a handful of other reporters currently on staff (he made a great Dilbert on Halloween), but the consistent level of typos, misspellings and various other mistakes (on a daily basis) goes way beyond what should be expected from a professional news organization. I know all about deadlines, and the occasional goof is expected to get by, but the continuous flow of embarrassing errors coming from this site is....well....just embarrassing!
Well... I cannot argue with that! The glitches are legion. The AP isn't any better, constantly violating its own rules of AP Style. My favorite: These kids who think "25-years-old" should be hyphenated, confusing it with, for instance, "a 25-year-old man." It's so basic and elementary, but they just don't get it... and it makes it online all the time. What happened to having copy editors, anyway? Sheesh.
We can figure out all this amazing stuff in space and yet we still cannot proof read a published article. Journalistic integrity has been lost in a giant black hole for years now........
God is going to be a busy little chappie turning off all the stars so that the "End of the World" occurs at just the right time. Oh, of course he was a busy little chappie several (lots of) light years ago.
nice video, somehow I thought centarus a was a lot closer to us than it is....oh well, time to send out a gaggle of imperial droid probes in that direction anyways, never know where the rebel alliance might be hiding.....
for those interested this is a link I stumbled upon while trying to find the 130 missing star systems page by RECONS...yea, I forgot proxima (Alpha Centauri) and Centaurus A have nothing in common, other than being in the S. hemisphere way outta my view........ http://www.chara.gsu.edu/RECONS/TOP100.posted.htm
I think you're confusing what "in Centaurus" means. The galaxy is in the constellation Centaurus, but not really IN it. If you look at that galaxy in the sky, you'll find it APPARENTLY within Centaurus. Don't confuse that with the star Alpha Centauri A (and Alpha Centauri B; it's a binary system, and Proxima Centauri, a third star, is likely gravitationally bound to that, so some argue it's a trinary system) which is PART of the constellation Centaurus. The trinary star system is very close, about 4.25-ish light years away. The galaxy in Centaurus, NGC 5128, is also called Centaurus A... but it is 10 to 16 MILLION light years away.
Alan, correct me if I've mucked anything up here.
Constellations are not 'places' but merely 'directions' in the sky. It's like saying your neighbor's house is in the 'north'. Even though your neighbors house is close, just across the street, that doesn't mean everything in the 'north' is across the street. There are things very far away in the 'north' too. Likewise, 'in Centaurus' just refers to those objects in the same general direction as the stars that make up what appears to be the outline of a centaur in the sky from here. Some are close, some are very, very far.
thank fitzpatrick and sciguy, of course I knew that, hope you all find the link helpful....I spared depriving you all the pleasure of googling for yourselves, the wikipedia pages are great but for anyone following up on research make sure to surf the external links as well...now on with the real comment, I am hoping nasa, grad students, and a long list of private, commercial and taxpayer funded astro-surveys as well as my fellow telescope gazers will focus a LOT more man-hours on the near neighbor-hood. I am as excited as anyone when hubble sees further something further out, and I am positive that studying dark holes, dark matter, dark energy and all else in totality and examining the self evident differentials (with and without the calculus) will expand our understanding of everthing, including ourselves, BUT...I think we are enamored with the forest and should take a closer look at the trees right in front of us...as pointed out in another post, where the cute black hole is in our viewfinder is far from where it actually is at this point in time...where as, not so with, as David points out, the very close trinary system!!.....the direction of our soon to be launched "imperial probe droids" will be very much determined by what small data we can garner over the next few decades...I AM CERTAIN that amatures will play a pivotal role in THAT data collection!!..why? because, my dear watsons, the easy pickens are easier to get funding for...not to say that the work in the article was "easy", and we all love pics and data analysis of black holes and their cosmic ejecta. So, In summary, I implore those with such interest to look hard and long in our near neighborhood...if there are signs of intelligence, it will be an order of magnitude more probable to detect, if there are dark stars, they will be hard to find but of major significance, also note the stars that have been close to us in the last 500 million years, if there is to be some possibility of transpermia, those stars have a higer degree of probability than say, a far flung galaxy....not to say one is more favored than the other, more like a common sense approach to the theory....and finally, quo vadis?...if not the trinary system or benards star of wolfs star then where?...like the moon, we shall reach for the closest star, unless something peculiar calls us in a different direction....which is why I jumped back here after loading the comment....
Black hole, jets, blehhh. We're probably just seeing that galaxy's 5/21/11 at 6:00 p.m. now. Of course, that happened a long time ago, and the date is far ahead, there, now. So prepare --- 6pm is coming!!!
How can a "Black Hole" emit anything? Isn't that a contradiction in terms......?
The material in the jets does not come from inside the event horizon, which would indeed be a contradiction. Scientists don't know exactly how the jets work, but one theory is that the distortion of the space and time around the hole as it rotates twists magnetic field lines at the poles in such a way that it accelerates in-falling material in the area and shoots it out along those magnetic field lines at high speed before it can enter the event horizon.
sci guy...what about the bubble off cygnus 1X - the data was described as a 'cavity of whatever eminating from 1X at a 'very fast speed' - and what about 'Hawkins Radiation' (these are real questions)? thanks
Yeah, aren't these black holes supposed to be all suck, no blow-back? Maybe there're not as perfect as they pretend to be.
The more I learn, the more I realize how little I know. This stuff is fascinating, Captain!
i blame Obama
Did Al Gore take this photo? If so then this is just another liberal hoax to get us to believe the universe is heating up due to intergallactic man-made radiation. Just another ploy to keep us from drilling into black holes to supply our country's energy needs. I'm not fooled for one second.
The implications are mind boggling. The indescribable forces at work to produce those jets. This is where black hole theory meets fact even though the black hole is not directly observable.
I have a black hole in my pants....
..and your brain
Looks like a creepy, conjoined twin fetal nightmare in the sky.
Centaurua A is placed well for observation from Southern California (although it's low in the south). It can be glimpsed after sunset twilight in the next few weeks IF you have a LOW south horizon, a VERY DARK sky , a good star map and a good telescope. I'm going to view Centaurus A this weekend, using a 120mm Refractor and try to image it too! I'll let you know if I'm zapped by the radiation.
